A waterway and system of waterways are disclosed in which the waterway comprises a sheet of material having an upper face which defines a central channel straddled by a pair of skirts, and a pair of spaced walls between the channel and skirts to define the channel. When positioned in the system, the skirts of the waterway are anchored to the soil and covered with soil, and surface water from the soil is collected and drained through the channel. The ribs have walls which extend upwardly from the upper surface of the waterway, are spaced from each other and have juncture lines extending their length to permit the ribs and sheet of material to flex and rebound without damage when exposed to substantial loads.
